Twenty-three diabetic patients with cerebral-thrombosis (DCT) and 16 cases without (D), 67 cases of nondiabetic cerebral thrombosis (CT), and 50 healthy subjects were investigated on the microcirculation of nailbed and conjunctiva with Model WX-7.53 microcirculation microscope. The results showed that all the patients had micro circulatory abnormality of nailbed, and,conjunctiva. The severity of microcirculatory abnormality was significantly different between these three groups of patients (P

本文介绍了北医大汉语失语成套测验（ABC）。根据10年失语症研究的经验总结出汉语失语症的主要类型及其鉴别论断要点，并根据复述、流利性、听理解及口头还是书面语言障碍这4个要素总结出鉴别各型汉语失语症的鉴别诊断流程图。指出失语症分型可为语言康复提供可靠依据，4个鉴别要素尚可提供大脑病灶定位信息。

It was introduced that the Aphasia Battery of Chinese (ABC), proposed by neurology department of Beijing Medical University. According to the experience of aphasia research for 1O years, we summarized the main types of Chinese aphasia and the differential diagnostic principles for them,and the differential diagnosis flow diagram of all major Chinese aphasia types was advanced according to the four principles-Ai repetition, fluency, auditory comprehension and oral or written language disorders. It was pointed out the classification of aphasia will provide the reliable basis for language rehabilitation and the four principles offer the information for localized lesions of brain.

Objective To delineate the changes in pattern and time course of semantic and phonological processing during Chinese language cognition study in patients with mild Alzheimer’s disease (AD) and mild cognitive impairment (MCI). Methods Patients with mild AD(n=32)and MCI (n=39) as well as normal controls (NC, n=40) matched with age, gender, level of education were enrolled in the study. Subjects completed Chinese compound word decision task applying both short and long stimulus onset asynchrony (SOA). Semantic, homophonic, semihomophonic and unrelated primes preceded the real words as well as nonwords targets. Subjects were asked to judge whether the targets were real words or nonwords. The reaction time and accuracy were recorded for each response. Semantic and phonological priming effects were analyzed by comparing the related primes versus unrelated primes. Analyses of variance (ANOVA) and t-test were conducted for reaction time and accuracy respectively. Results The mean reaction times of mild AD and MCI groups were prolonged (411 ms and 234 ms) for all types of priming in contrast with NC(P
